Technical Field

[0001] This utility model relates to the field of inductor manufacturing technology, and in particular to an inductor winding clamp. Background Technology

[0002] Inductor winding fixtures, as core tooling equipment in inductor manufacturing, are mainly used to fix the magnetic core or frame and assist in the precision winding of enameled wire. Traditional fixtures mostly adopt mechanical clamping structures, using cylinders or springs to press the two ends of the magnetic core, and guide wheels to control the copper wire path. However, these fixtures suffer from problems such as insufficient clamping accuracy and unstable tension adjustment, which can easily lead to winding deviation or damage to the enameled wire. With the increasing demand for miniaturization and automated production of inductors...

[0003] The existing application number CN202120511184.3 proposes an inductor winding clamp, including a worktable, a motor slot and a moving slot are provided in the worktable, a first rotating motor is fixedly connected in the motor slot, a second rotating shaft is provided in the moving slot through a bearing, a lead screw is fixedly connected between the second rotating shaft, and a slide rod is fixedly connected in the moving slot; Its beneficial effect is that the inductor winding fixture, through the first rotating motor, drives the second rotating shaft and the lead screw to rotate. The rotation of the lead screw drives the moving stage to the right, so that the position of the moving stage can be adjusted according to the length of the inductor frame. Through the second rotating motor, the gear, gear chain, first rotating shaft, turntable and inductor frame are rotated. However, the existing technology is relatively complicated to disassemble and install different inductor winding fixtures, and repeated calibration is required when changing to adapt to different specifications of magnetic cores, which leads to reduced production efficiency. In addition, it is easy to loosen due to vibration during the clamping process, which affects the winding accuracy. Utility Model Content

Detailed Implementation Example 1

[0011] This utility model provides an inductor winding clamp, characterized by including a workbench 1 with a mounting groove 5, multiple cooling fans 2 mounted on the mounting groove 5, multiple indicator lights 3 mounted on the side of the workbench 1, multiple stops 4 mounted on the workbench 1, and the workbench 1 and the stops 4 connected by bolts and nuts; a drive housing 6 housing a motor 10; an adjustment housing 7 mounted above the drive housing 6, with a cylinder 8 and a rotary valve 9 installed inside the adjustment housing 7; and a rotary valve 9 mounted on the side of the cylinder 8. A lifting platform 11 is installed inside the drive housing 6. A rotating rod 12 is connected to the lifting platform 11, passing through the drive housing 6 and connecting to the lifting platform 11. A rotating disk base 15 is mounted on the side of the connecting rod 13. A turntable 18 is mounted on the turntable base 15, and a connecting base 20 and multiple adjustable clamps 17 are mounted on the turntable 18. Adjustable clamps 17 are provided on the side of the connecting base 20.

[0012] When using this invention, the operator installs the coil frame 19, which requires inductor winding, onto the adjustable clamp 17. The coil frame 19 is connected to the connecting shaft of the connecting base 20 via its side. After installation, the other side of the coil frame 19 is fixed using the other adjustable clamp 17. Once the coil frame is securely clamped, the motor 10 is started. The PLC controller issues commands according to a preset program and turns on the cooling fan 2 in the workbench 1 to continuously provide cooling. The cylinder 8 pushes the adjustable clamp 17 to hold the coil frame and tighten the tension wheel to create constant tension. At this time, the tension sensor monitors the tension in real time and feeds the data back to the PLC controller, ensuring constant tension during winding. During operation, when stress concentration inside the coil is found to be caused by unidirectional torsion during inductor winding, the reverse rotation device is activated. The PLC controller controls the stepper motor driver to drive the stepper motor 22 to run. The stepper motor 22 rotates in the reverse direction, which drives the rotary valve A to open. The cylinder A adjusts the tension. For different coil frames 19, the adjustable clamp 17 can adjust the clamping force according to its size to ensure stable fixation while avoiding damage to the frame surface. At the same time, if the motor 10 or the stepper motor 22 needs to be replaced during continuous operation, different models of motors and motor sizes can be replaced. The height can be adjusted according to the lifting platform body 11 and the lifting platform assembly A through the rotating rod 12 and the rotating rod A24 to adapt to the installation requirements of different motors, which is more convenient and faster. Furthermore, the indicator lights 3 can reflect the equipment's operating status in real time. Green indicates normal operation, yellow indicates a warning message, and red indicates a fault and shutdown, making it easy for operators to grasp the working situation in a timely manner and take corresponding measures, thereby improving equipment management efficiency and safety.

[0013] This utility model can disassemble and install fixtures of different specifications according to different inductor coil processing requirements, adapting to the processing of various coil sizes. The fixture can effectively fix the coil frame and prevent position displacement caused by vibration during processing.
